问题描述
我正在尝试将文件上传到 SharePoint 2010:
I'm attempting to upload a file to SharePoint 2010:
Function Add-Attachments()
{
[CmdletBinding()]
Param(
[Parameter(Mandatory=$True)]
[int]$Id,
[Parameter(Mandatory=$True)]
[string[]]$Paths
)
BEGIN {}
PROCESS {
$url = "http://server/resource/_vti_bin/listdata.svc/TheList($Id)/Attachments"
Foreach ($Path in $Paths) {
Write-Verbose "Attaching $Path ..."
$headers = @{
'Slug' = "TheList|$Id|$(Split-Path $path -Leaf)"
}
$Payload = @{filename=(Split-Path $path -Leaf);filecontent=([IO.File]::ReadAllBytes($path))}
Invoke-WebRequest -Uri $url -Method Post -UseDefaultCredentials -Body $Payload -Headers $headers
} # Foreach
} # PROCESS
END {}
}
Add-Attachments -Id 1234 -Paths 'C:UsersgandalfDesktop est.txt' -verbose
我收到一条错误消息:
调用-WebRequest: 发生错误处理这个请求.在C:UsersgandalfDocumentsWindowsPowerShellScriptsSPSharePoint2010.ps1:382字符:13+ Invoke-WebRequest -Uri $url -Method Post -UseDefaultCredentials -Bod ...+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~+ CategoryInfo : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-WebRequest],网络异常+ FullQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeWebRequestCommand

该脚本确实在服务器上创建了一个文件，但内容如下:
The script does create a file on the server, but with this content:
filename=test.txt&filecontent=Lorem+ipsum+dolor+sit+amet%2c+consectetur+adipiscing+elit.+Donec+a+diam+lectus.+Sed+sit+amet+ipsum+mauris.+Maecenas+congue+ligula+ac+quam+viverra+nec+consectetur+ante+hendrerit.+Donec+et+mollis+dolor.+Praesent+et+diam+eget+libero+egestas+mattis+sit+amet+vitae+augue.+Nam+tincidunt+congue+enim%2c+ut+porta+lorem+lacinia+consectetur.+Donec+ut+libero+sed+arcu+vehicula+ultricies+a+non+tortor.+Lorem+ipsum+dolor+sit+amet%2c+consectetur+adipiscing+elit.+Aenean+ut+gravida+lorem.+Ut+turpis+felis%2c+pulvinar+a+semper+sed%2c+adipiscing+id+dolor.+Pellentesque+auctor+nisi+id+magna+consequat+sagittis.+Curabitur+dapibus+enim+sit+amet+elit+pharetra+tincidunt+feugiat+nisl+imperdiet.+Ut+convallis+libero+in+urna+ultrices+accumsan.+Donec+sed+odio+eros.+Donec+viverra+mi+quis+quam+pulvinar+at+malesuada+arcu+rhoncus.+Cum+sociis+natoque+penatibus+et+magnis+dis+parturient+montes%2c+nascetur+ridiculus+mus.+In+rutrum+accumsan+ultricies.+Mauris+vitae+nisi+at+sem+facilisis+semper+ac+in+est.
我错过了什么?我需要包括内容长度吗?设置 MIME 类型?
What am I missing? Do I need to include the content length? Set the MIME type?
推荐答案
为了创建附件资源，必须指定以下属性:
In order to create an attachment resource the following properties have to be specified:
Endpoint Uri: http://server/site/_vti_bin/listdata.svc/entityset(itemid)/Attachments
Method: POST
Headers:
Slug: "entityset|itemid|name"
ContentType: */*
Body: content
话虽如此，我的结论是指定的 body 参数 ($payload) 在提供的示例中无效.
Having said that, my conslution that the specified body parameter ($payload) is invalid in the provided example.
以下示例演示了如何通过 SharePoint 2010 REST 接口上传附件文件:
The following example demonstrates how to upload attachment file via SharePoint 2010 REST Interface:
Function Add-Attachments()
{
[CmdletBinding()]
Param(
[Parameter(Mandatory=$True)]
[string]$WebUrl,
[Parameter(Mandatory=$True)]
[string]$ListName,
[Parameter(Mandatory=$True)]
[int]$ItemId,
[Parameter(Mandatory=$True)]
[string]$SourcePath
)
BEGIN {}
PROCESS {
$endpointUri = New-Object System.Uri("$WebUrl/_vti_bin/listdata.svc/$ListName($ItemId)/Attachments")
$fileName = (Split-Path $SourcePath -Leaf)
$fileContent = ([IO.File]::ReadAllBytes($SourcePath))
$headers = @{
'Slug' = "$ListName|$ItemId|$fileName";
}
Invoke-WebRequest -Uri $endpointUri -Method Post -UseDefaultCredentials -Body $fileContent -Headers $headers -ContentType "*/*"
} # PROCESS
END {}
}
用法:
Add-Attachments -WebUrl "http://contoso.intranet.com/" -ListName "Tasks" -ItemId 1 -SourcePath "C:UsersuserDocumentsSharePointUserGuide.docx" -verbose
更新
通过 Fiddler 进行一些分析后，确定正确的端点 url 应该是:
After performing some analysis via Fiddler, it was determined that the proper endpoint url should be:
/_vti_bin/listdata.svc/Attachments HTTP/1.1
代替:
/_vti_bin/listdata.svc/Tasks(<id>)/Attachments HTTP/1.1
修改后的例子
Function Add-Attachments()
{
[CmdletBinding()]
Param(
[Parameter(Mandatory=$True)]
[string]$WebUrl,
[Parameter(Mandatory=$True)]
[string]$ListName,
[Parameter(Mandatory=$True)]
[int]$ItemId,
[Parameter(Mandatory=$True)]
[string]$SourcePath
)
BEGIN {}
PROCESS {
$endpointUri = New-Object System.Uri("$WebUrl/_vti_bin/listdata.svc/Attachments")
$fileName = (Split-Path $SourcePath -Leaf)
$fileContent = ([IO.File]::ReadAllBytes($SourcePath))
$headers = @{
'Slug' = "$ListName|$ItemId|$fileName";
}
Invoke-WebRequest -Uri $endpointUri -Method Post -UseDefaultCredentials -Body $fileContent -Headers $headers -ContentType "*/*"
} # PROCESS
END {}
}
